Video Power Tool

Video Power Tool turns many videos into a single, tidy wall.

Collect videos as you browse, then play them all at once on a grid that fits
itself to your screen. Drag a tile to move it, an edge to resize it, and the
rest reflow with no gaps. Pin one on top, minimise one away, zoom and pan, set
A–B loops to clip a video to just the part you want, and hold a tile to run
real-time AI upscaling (Anime4K on WebGPU). Drop in your own local video and
audio files too.

Right-click any video and choose "Add video to the wall" to capture it — works
on any page. For sites you visit often, open Site settings and add them: then a
Ctrl+click captures a post, and a download panel with a Merge button appears.
Everything stays on your device — no accounts, no tracking.
